You can join the list elements with String.Join() method instead of using a loop.

An example:

Dim list As New List(Of Integer) From {0, 1, 2, 3, 4, 5}

MessageBox.Show(String.Format("LocID: {0}", String.Join(", ", list)), _
                Nothing, MessageBoxButtons.OK, MessageBoxIcon.Information)
